The purpose of this utility model is to design the energy-conservation magnetic switch of a kind of bayonet type, pull-in winding holds back sealed and maintenance by snap close with the adhesive body when starting, need not give coil electricity in the course of the work, when discharging, by release coil snap close is opened release adhesive body, the adhesive body recovers under the effect of spring, thus realize energy-conservation, eliminate magnetic interference with the mechanical shaking interference with save production cost.
One end of the utility model reset tension spring is fixed on the housing, the other end is fixed on the adhesive body, pull-in winding is contained in an adhesive body side opposite with extension spring, one end of adhesive body connects adorns moving contact, snap close is contained in the homonymy of adhesive body and moving contact opposite end pull-in winding, snap close is contained on the housing with reed, and release coil is contained in snap close behind; When the adhesive body was lived in the pull-in winding adhesive, the end of adhesive body was slipped into snap close and is pinned by snap close, and when release coil adhesive snap close, snap close discharges the adhesive end of body.
Compared with prior art, the utlity model has following remarkable advantage:
1. energy-conservation.Only, in entire work process, need not energising starting and stop the Shi Caixu energising, thereby can saves energy, particularly remarkable for the occasion energy-saving effect that start and stop are not frequent.
2. the mechanical oscillation of not having the coil magnetic interference in the course of the work and producing because of power-supply fluctuation are to the interference and the influence of controlled device.
3. lead is not had specific (special) requirements, can save lead, reduce production costs.
4. owing to the utlity model has self-retaining function, can simplify line design, finish complicated logic function.
